Natural Gas CO2 burner opinions

[Big Tree]

I'm in the market for a natural gas CO2 burner that can have it's excess heat vented outside.
Can anyone give me their opinion on a reliable-safe unit that will work in a 1100 Sq. foot room.
There are so many companies popping up I want to get one that tried and true for both safety and effectiveness without breaking the bank.
Thanks friends.

I have 3 Blu Ox NG burners, 2 - 8 burner and 1 - 4 burner. All work great. Built in Maple Ridge, BC for greenhouse use. They require a small PVC/ABS pipe to bring fresh air to the ignition port. Gas inspector approved them without a hitch, I simply followed installation instructions. Good luck

I think the CO2 is in the excess heat so that shouldnt be vented. Extra A/C or using a watercooled heat exchanger is what is used to cool it. A natural gas water heater from eBay that has a pump on a CO2 controller to turn it on will remove a lot of heat, one must use a reservoir outside the room to dissisipate heat carried in the water away from the natural gas burners.

I have been looking at the hydrogen water cooled generators. I like the abilty to recirc or DTW cool the unit. Sleek and priced ok....plus with the accessories it looks almost like it wont add heat to the room at all or very negligible. I'd like to hear more opinions as well.
